If your computer is running slower than usual, showing unexpected pop-ups, or behaving strangely, it might have a virus. The most reliable way to check is to run a full system scan with trusted antivirus software. At Y-Not Tech Services in Lethbridge, we help seniors across Alberta identify and remove viruses safely. Never click on pop-ups claiming your computer is infected – these are often scams designed to trick you into downloading fake antivirus software.
